Solution of Own Window Pane Oscillation by Subspace Iteration Method

Solving building acoustic of structures leads to a requirement to know behavior of dynamically loaded structures. Often used design is a window, that glass pane can be modeled as board. When measuring acoustic qualities of windows, monitored value is frequency of excited sound as a sound pressure. From solutions of dynamically loaded structures is known fact that when excited frequency of load is equal, or approximately equal to its natural frequency, there is an unwanted resonance phenomenon.
